REMOVABLE-CAP ATTACHMENT.

l Application \\1ed October l, 1922. Serial No. 594,947.

To all whom t may concer/n.:

Be it known that I, GEORGE W. ITTNER, a vcitizen of the United States, and a resi dent of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Removable-Cap Attachments, of which the following is` a specification, reference being made to the accompanying drawings,` forming a part p thereof.

My invention relates particularly to that type of removable caps which are rotatably secured upon a screw-threaded nozzle comprising the open end of compressible tubes or receptacles for viscous substances such as tooth paste, shaving creams and the like, an the objects of my invention are, among other things, to provide an improved means for attaching'the cap to the receptacle or nozzle to prevent loss of the cap when removed or detached. For this purpose I have devised an improved link attachment for the cap which acts somewhat as a hinge or liexible joint with res ect to the o en nozzle by which the cap 1s allowed a ree.

to and fro movement from the nozzle only in a plane substantially coincident with the axes of the cap and nozzle. Such attachment holds the cap clear from the nozzle when the tube is to 4be compressed in use, and yet readily permits the vcap to be brought back' into screwing-on position. l Furthermore, my improved attachl ment may be easily s rung on or off both the cap and nozzle, an is rotatably or slidably secured to both members lwhile it may be rigidly held with either nozzle or ca while the one or the other is being rotate Another feature of my invention is that the attachment .may be economically manufactured for tubes or caps of any size and also` for nozzles of varying lengths by y'1ncorporating additional links in the attachment.

With these land other objects in view, my invention comprises the novel construction, combination and arrangement of parts to be hereinafter specifically described,4 and thereafter articularly pointed' out in the appended c aims. I attain the foregoing advantageous results by the ca attachment a preferred embodiment of wlhich is illustrated in the. ac-

companying drawings in which- Fig. l `is a side elevationshowing the cap in position to close the nozzle of the tube receptacle;

Fig". 2 1s a similar view showingthe cap Fig. 4 is an enlarged top plan view-with Vthe partsin the position shown in Fig. 2.

Similar numerals refer to similar parts throughout the several figures. d

Referring to the drawings, the tube or receptacle 5 has the shoulder 6 at its lupper or open end terminating in the nozzle 7 provided with the opening 8 through which the contents of .the tube 5 passes when the latter is compressed. The nozzle 7 is eX- teriorly screw-threaded at 9 and between the shoulder 6 and threads 9 I form the' annular groove 10 about the base of the nozzle 7 The cap 11 has the depending circular flange 12 interiorly threaded. as shown in Fig. 3 to coo erate with the nozzle threads 9 to hold t e cap 11, when rotated, to the nozzle 7. Encircling the iange 12 is the annular groove 13 adaptedto rotatably or slidably secure the ring or loop portion 14 of the rectangular link 15, pref- -erably formed of steel wire or other resilient material. Pivotally secured to the .ends 1.6 of the link 15 is the rectangular link 17 of similar material which is likewise pv. otally secured to the ends 18 and 19 of the ring 20 which is rotatably or slidably secured in the annular groove 10 `at the base ofthe nozzle 7 as shown in Fig. 4.v By this series of vpivotedvrectangular links 15 and 17 with the connecting ring 20 the .I

cap y11 is -secured to, and is rotatable laterally about, the nozzle 7, while the cap 11 itself may be twisted or turned in loop portion 14 of the link y15. has a free movement to an y zle 7 only in a plane substantially coincident with that of the axes of the nozzle 7 and cap 11. Additional links may be A ain the cap 11 from the nozembodied in my link attachment holding the cap 11 to the base ofthe nozzle 7 to accommodate for tubes having nozzles 'of greater length 'than that shown. The ring 20 is readily inserted on the nozzle 7 Y by frotating same through the screw-threads4 9'4 until `it snaps into position in the groove be readily sprung open to remove 'the cap 11 from the link 15.-

In operation, the cap" 11 is unscrewed and. when removed is held in the position shown in Figs. 2 and 4, the links 15 and 17 constituting a flexible joint or hinge to hold the cap away from the nozzle 7 as shown. Whenthe cap -11 is to be replaced, it is raised in substantially a vertical plane, and the links 15 and, 17 are folded upon each other as shown in Figs. 1 and 3, and the cap is screwed home.

It will be understood that the removable cap attachment herein shown and described maybe variously modified-'in details without departing from the principle and scope lof my invention as defined in the claims.

I claim as my invention:

1. The combination with apart to bev covered, of a cap therefor, and flexible means for loosely attaching said cap to said part, comprising a plurality 'of link members transversely hinged in spaced relationshipto both part and cap with the end members rotatably secured to each, whereby said cap may have a .bodily movement to and from said part only in a plane substantially coincident with the axes of the cap and part.

2. A. receptacle having an exteriorly screwthreaded nozzle, an interiorly threadedcap for Said nozzle, and means comprising a series of rectangular links transversely hinged in spaced relationship to both cap and nozzle for loosely attaching the cap to said nozzle, the end links being rotatably sev 'to both, said means permitting said ca to be moved to and from said nozzle only 1n a substantially vertical plane therewith.

4. A receptacle having an exteriorly screwthreaded nozzle with an annular groove about its base, an interiorly' threaded cap for said nozzle having an annular groove externally cut therein, and a series ofrectangular` links transversely pivoted at their spacedapart corners, the end links being slidably secured in said grooves for loosely attaching said cap to said nozzle to permit of a to and fro movement therebetween only in a plane substantially coincident with the axes of said cap and nozzle.
